WILLIAM EVANS, OF GALVESTON, TEXAS.

CHANNEL-CLEANER.

SPECIFICATION forming part of Letters Patent No. 426,254, dated April 22, 1890.

Application i'lled January 30, 1890. Serial No. 338,636. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM EvANs, of Galveston, in the county of Galveston and State of Texas, have invented a new and Improved Channel-Cleaner, of which the following is a specieation, reference being had to the annexed drawings, forminga part thereof, in Which- Figure l is a side elevation, partly in section, of my improved channel-cleaner. Fig. 2 is a vertical transverse section taken on line 2 2 in Fig. l, and Fig. 3 is an enlarged longitudinal section of one end of the cleanercasinfr.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to construct an apparatus which may be anchored in a channel Where there are sand-bars, for the purpose of agitatin g the water and stirring up the sand, so that the current may remove it.

My invention consists in a trunk or large tube perforated along the bottom and provided at one end With a flaring mouth for concentrating the current Within the trunk; also, in the combination, with the trunk, of a stirrer and a motor-screw for driving the same.

y The invention also consists in the combination,with the apertured end of the trunk, of valves for preventing the Water from backing into the trunk, all as will be hereinafter more fully described.

The cylindrical trunk A is formed of iron or other suitable material, and is provided with perforations a along the bottom thereof. One end of the trunk is closed with a perforated cap B, and the opposite end is enlarged, forming a flaring mouth C. The end of the flaring mouth C is furnished With a strainer i), for preventing the clogging of the apparatus.

In the trunk A is journaled a spiral screw D, and in the end of the trunk on a prolongation of the shaft of the sereWD is mounted a motor-screw E. The trunk A is held in place by anchors at opposite ends connected with the trunk by chains.

There the apparatus is used in harbors and rivers where the tide flows, the apertures a. of the trunk are provided with hinged valves c, which open outward, allowing the Water to pass out of the apparatus, but close when the flow of t-he Water is in the opposite direction. As thewater enters the flaring mouth O a porA tion of it passes out through the holes a in the bottom of the trunk, and the remainder passes out through the perforated cap B. rlhe current of Water passing through the trunk rotates the spirals D and also the'motor-screiv E. The rotation of the screw D agitates the Water in the trunk, and thus communicates motion to the Water outside of the trunk in the vicinity of the holes a, and the flow of Water through the said holes and around the outside of the trunk loosens the sand, so that it is carried along by the current.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a channel-cleaner, the combination of the perforated trunk A, provided with the flaring mouth O, and the screw D, journaled in the trunk, substantially as specified.

2. In a channel-cleaner, the combination of the perforated trunk A, the flaring mouth C, the strainer l), arranged over the daring mouth, and the spiral screWD, substantiallyas specified.

In a channel-cleaner, the combination of .the perforated trunk A, the spiral screw D,

and the motor-screw E, substantially as specilied.

Ll. In a channel-cleaner, the combination of the perforated trunk A, provided with valves c, and the spiral screw D, arranged to .revolve Within the perforated trunk, substantially as specified.

VILLIAM EVANS.
